8-Aminoquinoline amides of 3-oxo-olean-12-en-28-oic acid and 3-oxo-urs-12-en-28-oic were obtained characterized by 1H, 13C-NMR single crystal X-ray analysis. The used triterpenoic acids are oxidized forms naturally occurring oleanolic ursolic acids. Such types derivatives known for their anticancer antiviral activities. On the other hand, 8-aminoquinoline frequently transition metal complexatio...

The new triterpene saponin 3-O-beta-D-glucopyranoside, 28-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosiduronic acid oleanolate was isolated from the roots of Chenopodium ficifolium. The known compounds stigmasterol-3-O-glucoside and 3-O-beta-D-glucopyranosiduronic acid, 28-beta-D-glucopyranosyl oleanolate were also isolated. The latter compound, oleanolic acid, beta-sitosterol and its gluc...

in an attempt to develop alternative medicine for the treatment of diabetes and related complications, the antidiabetic potential of the fruits of c rataegus pinnatifida was evaluated. the antidiabetic potential of the methanol (meoh) extract as well as different solvent soluble fractions of the fruits of c . pinnatifida was evaluated via α-glucosidase, protein tyrosine phosphatase 1b (ptp1b), ...

Pentacyclic triterpenoic acids, betulinic acid, platanic oleanolic acid and ursolic were acetylated subsequently converted into mono-, bis- tris(hydroxyl)ethyl amides. While parent compounds are of none or minor cytotoxicity, these amides showed EC50 values even in low μM concentration for a variety different human tumor cell lines. Especially bis(hydroxyethyl)amide 12 derived from held an = 7....

Phytochemical works on the aerial parts of Aster oharai (Compositae) led to the isolation of a new sesquiterpene hydroperoxide, 7alpha-hydroperoxy-3,11-eudesmadiene (2) and seven known compounds, teucdiol B (1), alpha-spinasterol (3), oleanolic acid (4), alpha-spinasterol 3-O-beta-D-glucopyranoside (5), methyl 3,5-di-O-caffeoyl quinate (6), 3,5-di-O-caffeoylquinic acid (7), 3,4-di-O-caffeoylqui...
